CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rights application number 2016/1932, filed Aug. 8, 2016, which is herein incorporated by reference.

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Vanda spp. Jones ex R. Br.

Variety denomination: The inventive variety of Vanda disclosed herein has been given the variety denomination ‘SPCDW1602’.

BACKGROUND OF THE INVENTION

Parentage: The Vanda variety ‘SPCDW1602’ originated as a naturally occurring, whole-plant mutation of Vanda ‘SPCDW0902’ (U.S. Plant Pat. No. 23,343), a variety developed and owned by the inventor. The inventor of ‘SPCDW1602’ is a commercial ornamental plant producer and regularly discovers Vanda mutations at his greenhouse operation in Bangphra, Thailand. For said mutations which seem to exhibit commercial potential, cuttings are taken to produce trial plants which are subsequently grown for evaluation. This process resulted in the selection of a limited number of single plants with commercial potential. Micro propagation of said plants was initiated in the laboratory of breeder and limited amounts of trial plants were grown to the flowering stage, after which the positive characteristics were evaluated again. The variety now called ‘SPCDW1602’ was initially discovered at the inventor's greenhouse operation in Bangphra, Thailand in June of 2010 as one such mutation of ‘SPCDW0902’.

Asexual Reproduction: Asexual reproduction of the new cultivar ‘SPCDW1602’, by way of mericloning, was first initiated in August of 2010 at a commercial laboratory belonging to the inventor in Bangphra, Thailand. Access to all plants was restricted, as plants were kept in a greenhouse not open to the public, and tissue culture plantlets were in a laboratory belonging to the inventor, and not accessible to the public. Through six subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW1602’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘SPCDW1602’. These characteristics in combination distinguish ‘SPCDW1602’ as a new and distinct Vanda cultivar:

-   -   1. Vanda ‘SPCDW1602’ exhibits light pink sepals and lateral         petals which are margined with a darker shade of pink; and     -   2. Vanda ‘SPCDW1602’ exhibits sepals and lateral petals with         purple reticulate venation; and     -   3. Vanda ‘SPCDW1602’ exhibits a labellum with a dark pink         central lobe and light pink lateral lobes; and     -   4. Vanda ‘SPCDW1602’ exhibits a light pink column.

BOTANICAL DESCRIPTION OF THE PLANT

The following observations and measurements made in June of 2017 describe averages from a sample set of six specimens of six year-old ‘SPCDW1602’ plants grown in a greenhouse in Honselersdijk, the Netherlands. Temperatures were approximately 23 degrees Celsius during the day and 19 degrees Celsius at night. No photoperiodic or chemical treatments were given to the plants. No artificial light was given to the plants.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘SPCDW1602’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).
